VLC has no access to a mountpoints like ZFS filesystem mountpoint

[slrslr]

Hello,

I have https://github.com/ivan-hc/VLC-appimage/releases/download/continuous/VLC-media-player_3.0.21-2-archimage3.4-x86_64.AppImage

on Debian 11, KDE, Dolphin(file manager)

When I try to open the file from within VLC, then I am unable to browse beyond Downloads folder, other folders are gray/inactive.

File opened via Dolphin file manager: VLC GUI says: Your input can't be opened: ...

CLI:

[00007f7abc005eb0] filesystem stream error: cannot open file pathhere.mkv (No such file or directory)
dvdnav demux error: Couldn't find device name.

Please how to fix this? Any command line switch to use? AppImage file has executable permission.
